(CNN) Since the discovery of dark streaks on the slopes of Mars in 2011, astronomers have been excited about potential evidence of water beneath the surface of the red planet. If there are subsurface water flows on Mars, they could allow life -- even on a microbial level -- to exist as well. But further study of these recurring slope lineae, known as RSL, is revealing something else. Those dark streaks may be the result of granular flows like sand and dust, according to a study published Monday in the journal Nature Geoscience. The study is the product of a research team made up of representatives from the US Geological Survey, the Planetary Science Institute, the University of Arizona and Durham University in England.The flows correlate more with sand on active dunes rather than subsurface waterResearchers studied flows at 10 sites 
 Questions:Earth is the only analog we have for _, but Mars obviously behaves differently, the researchers said. (A) CNN (B) Mars (C) RSL (D) Nature Geoscience (E) US Geological Survey (F) Planetary Science Institute (G) University of Arizona (H) Durham University (I) England

Sailing can theoretically answer our family holiday brief - sunshine, beachcombing, local restaurants on a quayside, a sense of adventure. The only downer is that neither my wife nor I have a clue about sailing. So we decide that a Sunsail 'Flotilla Hero' holiday in Croatia, with a skipper provided, will fit the bill. Hopelessly ignorant of what to expect, we arrive at the Agana Marina, a 20-minute drive from Split, where our hostess, Rebecca, introduces us to 'Chilled', a fully equipped 47 ft yacht. Our temporary home is an instant hit with the children - Flora, aged eight, Celia, seven, and Tabitha, four.The waters off Croatia's long coast are ideal for summer sailing breaksFamily sailing holidays are possible, as boats stay in protective flotillasBoats can also come with experienced skippers to ensure safe progress 
 Questions:Celia stands on her tiptoes to see over the wheel as she tries to steer a steady course, while _ radios our progress to base with the sign-off, 'Chilled out', not quite reflecting the mood on-board. (A) Sunsail 'Flotilla Hero (B) Croatia (C) Agana Marina (D) Split (E) Rebecca (F) Chilled' (G) Flora (H) Celia (I) Tabitha

An innocent man who spent more than 30 years on death row for a murder he didn't commit has come face-to-face with the prosecutor who put him there. Glenn Ford, who was diagnosed with stage four lung cancer after his release last year, was too weak to stand when Marty Stroud walked into his Louisiana home last week but shook his hand. 'I want you to know that I am very sorry,' Stroud said during the somber meeting, which was filmed by Nightline. 'It's a stain on me that will be with me until I go to my grave.' 'Right,' Ford responded, without looking up. 'But it still cost me 31 years of my life and then nothing at the end but death because they give me from six to eight months to live.'Marty Stroud admitted in a letter published in a Louisiana newspaper last month that he was to blame for putting Glenn Ford behind bars in 1983Stroud: 'I was not as interested in justice as I was in winning'Ford, now 65, was freed a year ago after evidence emerged showing he was not at the scene of the murder and has since been living on donationsHe has also been diagnosed with stage 4 cancer and has months to liveStroud visited Ford's home to apologize to him face-to-face but Ford told him he was not able to forgive him 
 Questions:That, along with the money that he had in his bank account, left Mr _ with a paltry $20.24 to his name. (A) Glenn Ford (B) Marty Stroud (C) Louisiana (D) Stroud (E) Nightline
